[asim]

Please don't do go get -u. We have a specific go.mod file with versions that work.

[dwschulze]

Running go build main.go has the same effect.

@dwschulze @yezihack

maybe this issue can help you , This is a known issue between etcd and grpc
etcd-io/etcd#11563

you can replace grpc to v1.26+ or replace etcd to v3.3.4+incompatible in go.mod file, like this

// go.mod

replace google.golang.org/grpc => google.golang.org/grpc v1.26.0
// or
replace github.com/coreos/etcd => github.com/coreos/etcd v3.3.4+incompatible
